LOCK FOR BICYCLES.

SPECIFICATION formingpart of Letters Patent No. 599,143, dated February15, 1898.

Application filed August 25, 1897.

To all whom it may concern.-

Be it known that I, JOSEPH J. HALL, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have inventeda certain new and useful Improvement in Locksfor Bicycles and the Like, of which the following is a specification.

My invention relates to a new and useful improvement in looks forbicycles and the like, and has for its object to provide a simple,cheap, and effective device which may be readily attached to the frameof the machine and when desired for locking against unauthorized use maybe swung into position where it will automatically be secured, thusavoiding the use of a key for the locking of the bicycle, yet requiringa key for the unlocking of the same, and when the locking device is notin use the members thereof will in no wise interfere with the use of thebicycle, but do not have to be detached therefrom, so that when it isagain necessary to lock the machine this is accomplished without havingto remove the lock fromthe pocket or tool-bag.

With these ends in viewthis invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to 'make and use the same, itsconstruction and operation will now be described in detail, referring tothe accompanying drawings, forming a part of this specification, inwhich-- Figure 1 is a fragmental View showing a portion of a bicycle-wheel in section and locked by my improvement; Fig. 2, a View of aportion of one of the backstays of a bicycle, illustrating the method ofapplying my improvement thereto; Fig. 3, a section at the line 00 0c ofFig. 1, showing the locking device in its active position; Fig. 4, adetail section of the tumbler case, the hasp or swinging member beingengaged therewith; Fig. 5, a

cross-section of this case, showing the arrangement for securing it tothe frame of the machine; Fig. 6, a vertical section of thespring-casing, and Fig. -7 a cross-section thereof.

Serial No. 649,430. (No model.)

In carrying out my invention as here em bodied I provide two casings'Aand B, which have formed therewith the interlocking straps 5 5 0,whereby they are secured to the backstays by said straps having theirends hooked, as indicated at D, and a pin or key F being passed intoengagement with said hooked ends, as clearly shown in Figs. 2, 3, and 7.

The casing A has journaled therein a stud G, which is held in place bythe bolt H, having a nut I run upon its inner end, and this stud hascoiled therearound a spring J, the outer end of which is secured at K toa post within the casing, so as to give the stud a tendency to move inthe direction of the arrow marked adjacent thereto, and the movementofthis stud is limited by the pin L, projecting from the casing and setwithin the 79 field of rotation of two shoulders formed upon the lug.The outer end of the lug is flattened, as indicated at M, and has fittedthere on the locking-lever or hasp N, which is held in place by the headof the bolt H, from which it will be seen that when this lever is swungupward in the reverse direction of the arrow in Fig. 6 the tension ofthe spring will bein creased, so that when the lever is released it willagain resume its normally vertical posi- 80 tion.

The connection between the locking-lever and the stud is accomplished bysaid lever having a slot 0 formed therein, which will permit thelongitudinal movement of said lever for the purpose hereinafter setforth.

The casing B contains the lock proper and has pivoted therein a set oftumblers P, their lower ends being so formed as to readily engage thenotched end of the locking-lever, as indicated at Q, and this casing hasformed therein a slotted opening for the reception of the notched end ofthe locking-lever. Anotch R is formed in the upper edge of thelockinglever, so that when said lever is swung up- 5 ward this notch maybe carried into engagement with the-lower wall of the slot formed in thecasing B, and, as will be obvious, when the noses of the tumblers engagewith the end notch of the lockinglever after thenotch R has been carriedinto engagement with the slotted opening the locking-lever will be secured against displacement.

In order that the tumblers may be forced into engagement with the end ofthe lockinglever, a series of springs S, formed of sheetmetal platesproperly pierced, are secured within the casing B and bear against theheels of the tumblers, as clearly shown in Fig. 4:. By this arrangementit will be seen that when my improvement is attached to the rearstays ofa bicycle and it is desired to lock the bicycle against unauthorized useit is only necessary to swing the looking or hasp lever N upward, so asto cause it to pass between the spokes of the rear wheel, as shown inFig. 1, after which its free end is caused to enter into engagement withthe casing B, and the tumblers therein, as before described, will beheld crosswise of the rear wheel and between the spokes thereof, thusmaking it impossible to use the bicycle until the locking-lever has beenreleased and swung downward. The releasing of said lever may beaccomplished by a suitable key adapted to pass through the keyhole T andbe thrust against the varying ends U of the tumblers, by means of whichthe noses of said tumblers will be withdrawn m ng gement with thelockingr and the latter permit the swinging downward by the action ofthe spring J.

I do not wish to be limited to the use of a thrust-key, as this portionof the locking-case g m y b rr nged f r the eception of a turn-key, thetumblers being also fit-ted there.- for.

H ing t u u y described my inven ion, what I claim as new and usefulis..

1. In a device of the character described, two casings, each consistingof a top. and bot-. tom having their rear ends curved to conform to thecontour of the stay-bars of a bicycle,

front and back sections and a strap or band encircling the front andstay bar and forming the sides of the casing, a bolt journaled betweenthe front and back of one of said casings a p jec ing hr ugh. the f aStud on the bolt, a, spring coiled around the inner end of the stud, apost on the back and projecting through a concentric slot in the base ofthe stud, a locking-bar slotted at one end, said slot fitting over thestud, said stud being flattened so as to turn with the bar, and lockingmechanism in the other casing to engage the other end of thelocking-bar, as and for the purpose described.

2. In a device of the character described, two casings each consistingof a top and bottom having their rear ends'curved to conform to thecontour of the stay-bars of a bicycle, front and back sections and aband encircling the front section and stay-bar, forming the sides of thecasing and having a number of straps at its ends which are hooked backand interlock, a key run through the channel formed by these straps, alockdeVer secured to one casing and locking mechanism secured in theother for engaging the nose of the locking-lever, as and for the purposedescribed.

3. In a device of the character described, two casings, each consistingof a top and bottom having their rear ends curved to conform to thecontour of the stay-bars of a bicycle, front and back sections and astrap, or band encircling the front section and stay-bar forming thesides of the casing, a locking-lever pivoted within one casing, andlocking mechanism secured in the other casing for engagns the ose of thlockingas an f the purpose described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
